card)
The dimensions of the spacers included with communications option cards and those included with digital 16-bit
option cards differ slightly. See the following diagram when determining which spacers to use. Use of the wrong
spacers may damage the product.
(When connecting to A port)
(1) Install the digital 16-bit option, connecting it to the
D port (CN10) connector on the control printed
circuit board.
(2) Attach the two screws (a) included with the digital
16-bit option to mounting holes ① and ② on the
digital 16-bit option, and attach four spacers (b)
to
holes ③ through ⑥.
(3) Attach one spacer (d) included with the
communications option card to the option mounting
fixture (c) on the control printed circuit board.
(4) Install the communications option card so that
connector CN1 (on the back of the communications
option card) connects to
A port (CN3) on the
control printed circuit board.
(5) Tighten the three included screws (e) to secure the
communications option card in place.
(6) Referring to Figures 6.1.2 and 6.1.3, "Removing the
Front Cover," reverse the procedure to reattach the
front cover.
(When connecting to B port)
(1) Install the digital 16-bit option, connecting it to the
D port (CN10) connector on the control printed
circuit board.
(2) Attach the two screws (a) included with the digital
16-bit option to mounting holes ① and ② on the
digital 16-bit option, and attach four spacers (b)
to
holes ③ through ⑥.
(3) Attach one spacer (d) included with the
communications option card to the option mounting
fixture (c) on the control printed circuit board.
(4) Install the communications option card so that
connector CN1 (on the back of the communications
option card) connects to
B port (CN2) on the
control printed circuit board.
(5) Tighten the three included screws (e) to secure the
communications option card in place.
